If you have itchy eyes caused by allergies, your healthcare provider may prescribe Lastacaft. This medication comes in the form of an eye drop and is approved for use in adults and children as young as two years old. It works by blocking certain receptors in the body that produce histamines. At this time, there are no off-label reasons to use Lastacaft.
What Is Lastacaft Used For?Lastacaft™ (alcaftadine) is an antihistamine eye drop used for treating eye allergies.
Allergies can affect various parts of the body. Eye allergies are known medically as allergic conjunctivitis, because the allergic reaction occurs in the conjunctiva (the thin layer that covers the eye). Symptoms may include:
- Watery eyes
- Redness of the eyes
- Itchy eyes
- Puffy eyes
- Stinging and burning of the eyes.
Like most eye allergy medications, Lastacaft is approved for treating only the itching caused by eye allergies, not any of the other symptoms.
Allergy treatment can make life bearable for even the worst allergy sufferer, especially when combined with strategies to minimize a person's contact with allergens. Treatment often includes allergy eye drops, such as Lastacaft.
Unlike over-the-counter (OTC) decongestant eye drops, you can use Lastacaft long-term without the risk of making the redness and swelling worse by using it for too long.
How Does Lastacaft Work?Lastacaft belongs to a class of drugs called antihistamines. Specifically, it is an H1 receptor antagonist. This means that it blocks a specific type of histamine receptor in the body known as H1 receptors. Because allergic reactions are partly caused by the release of histamine from certain cells in the body, using Lastacaft can help relieve or prevent allergy symptoms.
In addition to blocking histamine receptors, Lastacaft may decrease the release of histamine from cells in the body.
